Just a week before its Samsung Mobile Unpacked 2012 event where it will announce "the next galaxy smartphone," Samsung has officially announced what SoC will be inside. The answer is Exynos 4 Quad, which is no doubt the Exynos 4412 we've heard about before. Exynos 4 Quad is built on Samsung's 32nm HKMG process and consists of 4 ARM Cortex A9s running at up to 1.4 GHz. Samsung reports 20% lower power with Exynos 4 Quad over Exynos 4 Dual (4210), though it doesn't say at what clocks or workload. In the past, Samsung has claimed 40% lower power on 32nm HKMG compared to their 4xnm process.
